Central Ontario is one of Ontario's most active areas for truck owners, with 52,000 residents near Ontario Convention Center and Holt Blvd. Central Ontario has a large commercial vehicle population — we regularly serve contractors and fleet operators from this area. We specialize in LINE-X spray-on bed liners and protective coatings, along with a full range of truck accessories, including bed covers, side steps, running boards, toolboxes, contractor racks, and more. We proudly offer LINE-X and other top-name brands, all backed by manufacturer warranties. Our 10,000 sq. ft. facility at 9261 Bally Ct in Rancho Cucamonga is about 10 minutes from Central Ontario — close enough for a same-day appointment on most quality suspension upgrade jobs.

The Inland Empire contains over 600 million square feet of industrial space, with Ontario at the geographic center. Ontario International Airport moved 875,000+ metric tons of cargo in recent years, and the I-10/I-15 interchange near Ontario processes among the highest freight volumes in North America. Fleet operators, freight contractors, and airport ground-support vehicles in the 91761 area need bed liners that survive shift-after-shift loading — LINE-X is the standard for commercial durability.
Ontario summer highs reach 95–105°F with EPA UV Index ratings of 10 or higher — classified Very High to Extreme. At those levels, unprotected steel beds oxidize faster, factory paint delaminates, and moisture-trapping drop-in liners accelerate rust underneath. LINE-X's UV-stabilized formulation is specifically engineered for Inland Empire conditions.
California Vehicle Code § 23114 makes drivers liable for materials that spill from truck beds onto roadways — a real concern on the I-10 and I-15 freight corridors through Ontario. A LINE-X liner creates a contained, non-slip surface that reduces cargo shift and prevents bed deterioration that leads to spillage violations.

We serve these nearby locations for suspension upgrade:
“Had Bilstein 5100s installed front and rear on my 4Runner. The difference in ride quality on the highway is night and day. Empire's guys know suspension — they explained exactly why they recommended the specific valving for my setup.”
“I came in with sagging rear springs on a heavily loaded work truck. Ryan diagnosed it in 5 minutes and had me sorted with new Rough Country add-a-leafs the same day. Back to riding level and hauling without bottoming out.”
“Jake did the Fox suspension build on my Tacoma and it's transformed the truck. Incredible off-road capability and way better on-road comfort. Worth every dollar.”
